Minn. R. Crim. P. 9.04
In misdemeanor cases, before arraignment or at any time before trial the prosecutor must, on request and without a court order, permit the defendant or defense counsel to inspect the police investigatory reports.
Upon request, the prosecutor must also disclose any material or information within the prosecutor's possession and control that tends to negate or reduce the guilt of the accused as to the offense charged.
After arraignment and on request, the defendant or defense counsel must be provided a copy of the police investigatory reports.
Any other discovery must be by consent of the parties or by motion to the court.
The obligation to provide discovery after arraignment may be satisfied by any method that provides the defendant or defense counsel a copy of the reports, including any electronic means available to both parties.
